poisonous plants
plants which contain specific chemical poisons, although they may not be identified. They are a different group from plants which cause illness if eaten in very large amounts or have physical qualities that cause illness, e.g. clover in bloat, tree loppings in omasal impaction. There is a third group of plants, those that are only intermittently poisonous. These form a very large group known to have caused nitrite, cyanide or oxalate poisoning but are valuable plants and are safe if used with care. See also under the names of individual plants or the toxins that they contain.
